Product-specific hazard symbols and warnings not covered in this section may appear throughout the body of this

manual where applicable.

DANGER

SEVERE ELECTRIC SHOCK HAZARD

This equipment is powered by more than 240V. Contact with this voltage will cause death or serious

injury.

• Turn off and disconnect the power at the main switch before disconnecting any cables and before

servicing equipment.

• This equipment must be grounded. Connect only to a grounded power source.

• All electrical wiring must be done by a qualified electrician and comply with all local codes and

regulations.

WARNING

FIRE AND EXPLOSION HAZARD

Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. Paint or

solvent flowing through the equipment can cause static sparking. To help prevent fire and explosion:

• Use equipment only in well-ventilated area.

• Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and plastic

drop cloths (potential static sparking).

• Ground all equipment in the work area. See Grounding instructions.

• Keep work area free of debris, including solvent, rags, and gasoline.

• Do not plug or unplug power cords, or turn power or light switches on or off when flammable fumes

are present.

• Use only grounded hoses.

• Hold gun firmly to side of grounded pail when triggering into pail. Do not use pail liners unless they

are anti-static or conductive.

•Stop operation immediately if static sparking occurs or you feel a shock. Do not use equipment

until you identify and correct the problem.

• Keep a working fire extinguisher in the work area.

Warnings

6 3A7826A

PRESSURIZED EQUIPMENT HAZARD

Fluid from the equipment, leaks, or ruptured components can splash in the eyes or on skin and cause

serious injury.

• Follow the Pressure Relief Procedure when you stop spraying/dispensing and before cleaning,

checking, or servicing equipment.

• Tighten all fluid connections before operating the equipment.

• Check hoses, tubes, and couplings daily. Replace worn or damaged parts immediately.

EQUIPMENT MISUSE HAZARD

Misuse can cause death or serious injury.

• Do not operate the unit when fatigued or under the influence of drugs or alcohol.

• Do not exceed the maximum working pressure or temperature rating of the lowest rated system

component. See Technical Specifications in all equipment manuals.

• Use fluids and solvents that are compatible with equipment wetted parts. See Technical

Specifications in all equipment manuals. Read fluid and solvent manufacturer's warnings. For

complete information about your material, request Safety Data Sheets (SDSs) from distributor or

retailer.

• Do not leave the work area while equipment is energized or under pressure.

• Turn off all equipment and follow the Pressure Relief Procedure when equipment is not in use.

• Check equipment daily. Repair or replace worn or damaged parts immediately with genuine

manufacturer's replacement parts only.

• Do not alter or modify equipment. Alterations or modifications may void agency approvals and

create safety hazards.

• Make sure all equipment is rated and approved for the environment in which you are using it.

• Use equipment only for its intended purpose. Call your distributor for information.

• Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot surfaces.

• Do not kink or over bend hoses or use hoses to pull equipment.

• Keep children and animals away from work area.

• Comply with all applicable safety regulations.

MOVING PARTS HAZARD

Moving parts can pinch, cut, or amputate fingers and other body parts.

• Keep clear of moving parts.

• Do not operate equipment with protective guards or covers removed.

• Pressurized equipment can start without warning. Before checking, moving, or servicing

equipment, follow the Pressure Relief Procedure and disconnect all power sources.

TOXIC FLUID OR FUMES HAZARD

Toxic fluids or fumes can cause serious injury or death if splashed in the eyes or on skin, inhaled, or

swallowed.

• Read Safety Data Sheets (SDSs) to know the specific hazards of the fluids you are using.

• Store hazardous fluid in approved containers, and dispose of it according to applicable guidelines.

WARNING

Warnings

3A7826A 7

BURN HAZARD

Equipment surfaces and fluid that is heated can become very hot during operation. To avoid severe

burns:

• Do not touch hot fluid or equipment.

PERSONAL PROTECTIVE EQUIPMENT

Wear appropriate protective equipment when in the work area to help prevent serious injury, including

eye injury, hearing loss, inhalation of toxic fumes, and burns. Protective equipment includes but is not

limited to:

• Protective eyewear, and hearing protection.

• Respirators, protective clothing, and gloves as recommended by the fluid and solvent

manufacturer.

Installation

Hazardous Location Cabling

and Conduit Requirements

Explosion Proof Requirements

All electrical wiring in the hazardous locations must be

encased in approved explosion-proof conduit that is

suitable for Class I, Division I, Group C and D locations.

Follow all national, state, and local electrical codes and

regulations.

US and Canada Conduit Location Requirement:

Install a conduit seal within 457 mm (18 in.) of the motor

enclosure.

Cable Rating Requirement: Use cables with a

minimum rating of 70°C (158°F).

Use appropriate conduit, connectors, and cable glands

rated for Ex II 2 G. Follow all national, state, and local

electrical codes and regulations.

Cable Rating Requirement: Use cables with a

minimum rating of 70°C (158°F).

Power Requirements

The system requires a dedicated circuit protected with

a circuit breaker in each ungrounded phase.

Location Requirements

• There must be sufficient space on all sides of the

equipment for installation, operator access,

maintenance, and air circulation.

• The mounting surface and mounting hardware

must be strong enough to support the weight of the

equipment, fluid, hoses, and stress caused during

operation.

• There must be an electrical disconnect (A) within

easy reach of the equipment. See FIG. 1 Typical

Installation, page 8.

Mount the Pump

Follow the instructions in the pump mounting kit

manual to mount the pump on a stand or on the wall.

See Related Manuals, page 3.

Stand Mount

1. Use the Floor Stand Mounting Pattern, page 35.

2. Bolt the stand to the floor with M19 (5/8 in.) bolts.

Use bolts that engage at least 152 mm (6 in.) into

the concrete floor to prevent the pump from

tipping.

3. Use shims to level the pump if needed.

Installation of this equipment involves potentially

hazardous procedures. Only trained and qualified

personnel who have read and who understand the

information in this manual should install this

equipment. All electrical wiring must be done by a

qualified electrician and comply with all local codes

and regulations.

Wall Mount

1. Use the wall mount bracket as a template.

NOTE: The bracket has two mounting hole groups. See

Mounting Bracket Pattern, page 34

2. Drill four 7/16 in. (11 mm) holes into the wall. Bolt

the bracket securely to the wall. Always use bolts

and washers designed to hold in the wall’s

construction.

3. Attach the pump assembly to the mounting

bracket.

Required System Accessories

•Electrical disconnect (A): Required in the system

to disconnect and isolate electricity from the motor.

•Start stop switch (E): Temporarily runs or stops

the motor. Must be approved for hazardous

locations.

Required Fluid Line Accessories

Install accessories as shown in FIG. 1, using adapters

as necessary. Make sure they meet the system’s size

and pressure rating requirements. See Technical

Specifications, page 36.

•Fluid drain valve (B): Required in the system to

relieve pressure in the hose and circulation system.

•Fluid shutoff valve (C): shuts off fluid flow.

Grounding

Static Grounding

Use a ground wire (G) to connect the motor to a true

earth ground.

1. Loosen the ground screw.

2. Insert a ground wire (G).

3. Tighten the ground screw securely.

4. Connect the other end of the ground wire (G) to a

true earth ground.

The equipment must be grounded to reduce the risk

of static sparking and electric shock. Electric or static

sparking can cause fumes to ignite or explode.

Improper grounding can cause electric shock.

Grounding provides an escape wire for the electric

current.
